According to the literature on Environmental Policy Integration (EPI), decisionmaking in complex domains of environmental policy—of which climate change is a prime example—tend to fragment and silo into individual dimensions of a problem. Scientific Advisory Committees (SACs) have been widely used to promote more integrated decisionmaking. SACs are intended to integrate the varied, and often fragmented, dimensions of policy problems, and this integration is widely believed to enable more effective use of science in climate change policy. This paper empirically evaluates the degree of integration achieved through SACs in two national climate policy contexts: Germany and Japan. Network analysis is used to examine the myriad scientific advisory committees focused on climate change policy in these nations (N = 218), and quantify the degree of vertical integration (integration among different sectors) and horizontal integration (integration among different governmental bodies). Results show greater vertical integration among German SACs than Japanese SACs, and similar levels of horizontal integration between the two nations despite having very different structures. Such efforts to empirically connect the conceptual discussion of integration in EPI with empirical observations of integration in actual climate policy processes is an important step towards understanding the strategies that may be used to promote more integrated decisionmaking in climate change policy.
